Questions tagged [environment-variables]
Environment variables are system-wide variables which share the same value. These variables are often parsed by the shell when executing commands, and are expanded into their appropriate variable. For example, this allows users to move file locations without needing to update hard-coded paths in scripts (they just have to update the environment variable).
